Duh, I did it again, didn't I?  I'm constantly mixing up my
personal de domain with cygwin.com.  Sorry about that!

Apparently you only updated the Cygwin DLL, not the entire package
including the utilities packed with the DLL.  However, see the important
parts of my reply you snipped away:

  Cygcheck is a native Windows executable and thus does not use Cygwin's
  ^^^^^^^^                                         ^^^^^^^^^^^^^^^^^^^^^
  path handling (in contrast to md5sum, for instance).  Rather it uses a
  ^^^^^^^^^^^^^                                                ^^^^^^^^^
  home grown version and this in turn has a bug when checking the cygdrive
  ^^^^^^^^^^^^^^^^^^^
  prefix against the incoming path.  Everything goes, just not '/' alone.

So the patch I applied affected cygcheck, not the Cygwin DLL.
